Description

The MINGDA AD-F4 Pro is a large-format printer for efficient production of illuminated letters and 3D signage. It has a wide 1200 × 800 mm build area, a 4-color IMS feeding system with automatic color change and the proprietary MINGDA Slicer software for font generation, vector file reading and 2D to 3D conversion. An air-heated bed, 3rd-generation automatic leveling and Input Shaper vibration control complete the setup.

For reference, an 800 × 765 × 80 mm light box letter in PDS prints in about 8 hours at 200 mm/s, compared with about 40 hours at 50 mm/s on standard letter printers. These are experimental figures, for guidance only.

Frequently asked questions

What is the build area?

1200 × 800 × 100 mm, suited to large letters and signage.

How many colors can it print?

It prints up to four colors with the IMS feeding system, which changes color automatically.

How much faster is it than a standard letter printer?

MINGDA states it is five times faster. In an experimental example, an 800 × 765 × 80 mm letter prints in about 8 hours at 200 mm/s instead of about 40 hours at 50 mm/s. The figures are for guidance only.

Can I generate letters directly in the software?

Yes. The MINGDA Slicer supports font generation, vector file reading and 2D to 3D conversion.

What firmware does it run?

It runs Klipper firmware, with automatic 3rd-generation leveling and Input Shaper vibration control.
